The book Luoyang Galand is true, and the author is Yang Xuanzhi of the Northern Wei Dynasty. However, the story told in the song "Fireworks Easy to Cold" is called "Garland Ningyu", which is based on the biography of Luoyang Galand by Fang Wenqing (it is not clear whether it was invented according to the name or according to the main line of the story triggered by the war in the Southern and Northern Dynasties in the book), so it is not true.
Extended data
Galand in Luoyang, Galand for short, is an ancient Buddhist history book in China. It is a story note of historical figures written by Sima Yangxuan, a retired army, who revisited Luoyang more than ten years after the Eastern Wei moved the capital to Yecheng, remembering the prosperity of Buddhist temples in the suburbs before the robbery and summing up historical changes. It was written in 547 AD (Wuding five years in the Eastern Wei Dynasty).
Later generations called Luoyang Galand, Li Daoyuan's Notes on Water Mirror, and Yan Zhitui Yanshi's Family Instructions as the three masterpieces of China Northern Dynasties.
This book has been recorded in the official history of past dynasties, but its ancestor has long been lost. Now, all the "Luoyang Galand Tales" are based on the Song Dynasty, and their origins are quite mixed. Sikuquanshu listed it in the geographical category of the History Department.
Many achievements have been made in the study of this book since the 20th century, especially in literature, history, urban planning and architecture. It is generally believed that the book still has great research space in the fields of religious Buddhism, medieval literature, linguistics, and the history of cultural exchanges between China and foreign countries. In terms of communication influence, The Biography of Luoyang Galand has been translated into Japanese, Korean, English and other languages for a long time, which has a certain position in the international sinology community.
In addition, the song Fireworks Easy to Cold, written and interpreted by musicians vincent fang and Jay Chou, also spread for some time, which expanded the influence of the book to some extent.
